Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forestsin these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken inby the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone (臭氧) levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling."We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere." Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.（1）According to the new findings, taking steps to prevent northern forest fires may ________.A. result in a warming climateB. cause the forest fires to occur more frequentlyC. lead to a longer fire seasonD. protect the forests and the environment there（2）The following are all the immediate effects after a forest fire EXCEPT ________.A. large amounts of greenhouse gases enter the atmosphereB. the levels of ozone which is a type of oxygen increaseC. snow on the ground mirrors more sunlight back into spaceD. ashes from the fire fall on the ice surface and take in more radiation from the sun（3）Earlier studies about northern forest fires ________.A. analyze all aspects of how northern fires influence climateB. indicate that forest fires will pollute the atmosphereC. suggest that people should take measures to protect the environmentD. suggest that the fires will speed up climate warming（4）The underlined phrase "soak up" in the last paragraph most probably means ________.A. releasedB. absorbedC. createdD. distributed（5）From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ________.A. warm the climate as the supposition goesB. allow more snow to reflect more sunlight into space and thus cool the climateC. destroy large areas of forests and pollute the far-off sea iceD. help to gain more energy rather than release more energy【答案】（1）A（2）C（3）D（4）B（5）B【解析】【分析】本文是一篇说明文，介绍了阿拉斯加、加拿大和西伯利亚的森林大火使气候变暖，科学家们已经发现，在燃烧的树木允许更多的雪将更多的阳光反射到太空的地区可能会发生冷却。

An international team of researchers from the University of Oxford have found that the way people use the Internet is closely tied to the seasonal movements in the natural world. Their online species searches follow the patterns of seasonal animal migrations (迁徙).Migratory birds (候鸟) flood back to where they reproduce every spring. That migratory behavior is accompanied by some human behavior. "In English-language Wikipedia (维基百科), the online searches for migratory species tend to increase in spring when those birds arrive in the United States," said the lead author John Mittermeier.And not just birds. Mittermeier and his team surveyed nearly 2.5 billion Wikipedia search records, for 32,000 species, across 245 languages. They also saw variable search rates for insects, horsetails and flowering plants. Seasonal trends seemed to be widespread in Wikipedia behavior for many species of plants and animals.This finding suggests new ways to monitor changes in the world's biological diversity. It also shows new ways to see how much people care about nature, and which species and areas might be the most effective targets for conservation.Mittermeier is encouraged by the search results. He commented, "I think there's a concern among conservationists (生态环境保护者) that people are losing touch with the natural world and that they're not interacting with native species anymore. And so in that sense, it was really exciting and quite unexpected for me to see people's Wikipedia interest closely related to changes in nature."Richard Grenyer, Associate Professor from the University of Oxford, says search data is useful to conservation biologists, "By using these big data approaches, we can direct our attention towards the difficult questions in modern conservation: which species and areas are changing, and where are the people who care the most and can do the most to help."（1）What have researchers found about species searches?A.They strengthen ties among people.B.They affect the animal movements.C.They differ in language backgrounds.D.They reflect animal migration seasons.（2）What is the purpose of writing Paragraph 3?A.To summarize the research process.B.To further support the research findings.C.To show the variety of species searches.D.To present researchers' heavy work load.（3）How does Mittermeier feel about the search results?A.Satisfied with Wikipedia's service.B.Worried about Wikipedia behavior.C.Amazed at people's care about nature.D.Sad about people's not getting close to nature.（4）Why does Richard think such search data is useful?A.It helps to aim at conservation targets.B.It increases interest in big data approaches.C.It keeps track of trends in biologists' work.D.It pushes people to solve difficult problems.【答案】（1）D（2）B（3）C（4）A【解析】【分析】本文是一篇说明文，牛津大学的一个国际研究小组发现，人们使用互联网的方式与自然界的季节性运动密切相关。

While every dog owner knows their dogs can read their moods perfectly, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That's because the scientists believe humans show their emotions on their entire face.After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed.The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touch-screen models were all females, this confirmed what has been observed in previous studies dogs are more efficient at reading facial expressions of people that are the same gender as their owner.（1）How did the scientists conduct the experiment?A.By leaving dogs to women who are either happy or angry.B.By mixing the selected dogs together.C.By rewarding only half of the dogs touching the screenD.By showing digital pictures of women's happy or angry faces.（2）The underlined word "trepidation" in Paragraph 5 probably means ________.A.fear and hesitationB.curiosity and eagernessC.excitement and happinessD.doubt and sadness（3）According to the last paragraph, dogs with female owners ________.A.are fond of the male facesB.are uninterested in telling the emotions on the entire facesC.have difficulty telling the moods on the faces of malesD.can only recognize emotions of females（4）What is the best title for this passage?A.Mood Changes Influence DogsB.Dogs Identify the MoodsC.dogs and Their OwnersD.Dog's Mood Research【答案】（1）D（2）A（3）C（4）B【解析】【分析】本文是一篇说明文，最新的实验发现，即狗能够识别人的面部表情的变化。

A shark moving around the coastline is normally a worrying sight，but this waterborne drone (无人机) threatens floating rubbish instead of people.Developed by Dutch company RanMarine, the WasteShark takes nature as its inspiration withits whale shark-like mouth. Responsible for collecting waste, the drone will begin operations in Dubai Marina in November after a year of trials with local partner Ecocoast.According to RanMarine, the WasteShark is available in both autonomous and remote-controlled models. Measuring just over five feet by three-and-a-half feet (1.5 meters by 1.1 meter), it can carry up to 352 pounds of rubbish (159.6 kg) and has an operational battery life of16 hours.By 2016 there were approximately 150 million tons of plastic in the world's oceans. One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollutionwas afloat."WasteShark also has the abilities to gather air and water quality data, remove chemicals out of the water such as oil, and heavy metals, and scan the seabed to read its depth and outlines," said Oliver Cunningham, one of the co-founders of RanMarine. "Fitted with a collision-avoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches.""Our drones are designed to move through a water system, whether it's around the perimeter(周边) or through the city itself. The drones are that last line of defense between the city and the open ocean," added Cunningham. "WasteSharks are operating in Dubai, South Africa and the Netherlands and cost $ 17, 000 for the remote-controlled model and just under $ 23, 000 for the autonomous model."Dubai-based operator Ecocoast has two WasteShark drones. Co-founder Dana Liparts says they will clean waterfronts for clients including hotels and environmental authorities and that Ecocoast' intention is to have the collected rubbish recycled or upcycled. However, Liparts argues that cleaning waterways doesn't have a one-size-fits-all solution and requires a combination ofnew technology, preventative measures and changing people's attitudes towards littering.（1）What do we know about the WasteShark?A. It can frighten sharks away.B. It is an ocean explorer.C. It is a rubbish collector.D. It can catch fish instead of people.（2）What does Paragraph 4 mainly tell us?A. The causes of ocean pollution.B. The dangers of using plastics.C. The severity of ocean garbage pollution.D. The importance of ocean protection.（3）What will the WasteShark do with an approaching object?A. Avoid crashing into it.B. Break it into pieces.C. Swallow it.D. Fly over it.（4）Which of the following ideas does Liparts agree with?A. The WasteShark should be used more widely.B. More measures should be taken to make water clean.C. The production cost of WasteSharks should be reduced.D. People should take a positive attitude to new technology.【答案】（1）C（2）C（3）A（4）B【解析】【分析】本文是一篇说明文，介绍一种水上无人机可以用于清理浮在水面上的垃圾。

Gardeners such as Prince Charles who claim that talking to plants encourages them to grow have long been seen as a little silly. But scientists have discovered evidence which suggests the Royal may actually be right and they could be listening to him. Biologists at Tel Aviv University in Israel have found that flowers can act as a plant's "ears" to help them detect the sound of approaching insects.When the researchers played recordings of flying bees to evening primrose flowers, within three minutes the sugar concentrations in the nectar (花蜜) of its flowers increased. The fluid, produced to attract pollinating (授粉) insects, was on average 20 percent higher in flowers exposed to the buzz compared to those left in silence or exposed to higher pitched sounds. Professor Lilach Hadany, who led the study, said: "Our results document for the first time that plants can rapidly respond to pollinator sounds in an ecologically relevant way."However, Prof Hadany said a plant's ability to respond to pollinators may be weakened in city environments or beside a busy road. While plants require water, sunlight and the right temperature to grow, it is widely believed they do not have senses in the way animals do.But the study, published on the open-science website BioRxiv, suggests the efforts of gardeners who talk to their plants may not be in vain. "Plants' ability to hear has implications well beyond pollination—plants could potentially hear and respond to herbivores, other animals, the elements, and possibly other plants," Prof Hadany added.A month-long experiment conducted by the Royal Horticultural Society in 2009 found female voices appear to speed up the growth of tomatoes. The research offers a possible explanation —women's voices were at the right frequency for the plants to hear.（1）What's evening primrose flowers' response to bees' buzz?A. Longer bloom.B. Sweeter nectar.C. Brighter color.D. Less fluid.（2）Where can plants grow better according to Hadany?A. On a square.B. Beside a highway.C. In the woods.D. Along the street.（3）What can we infer from the research?A. Prince Charles proves kind of stupid.B. Plants can only potentially hear animals.C. Plants respond to sounds slowly and ecologically.D. Plants gardeners talk to frequently develop well.（4）What does the text mainly talk about?A. Flowers can hear.B. Bees are best pollinators.C. Plants can't grow without sound.D. Women's voices improve plants' growth.【答案】（1）B（2）C（3）D（4）A【解析】【分析】本文是一篇说明文，介绍了人与植物的交流可以促其生长。

Robots are now being employed not just for dangerous tasks, such as discovering mines or rescuing people in disasters. They are also finding application as household helps and as nursing assistants. As increasing numbers of machines, equipped with the latest artificial intelligence, take on a growing variety of specialized and everyday tasks, the question of how people see them and behave towards them becomes ever more urgent.A team led by Sari Nijssen of Radboud University and Markus Paulus, Professor of Developmental Psychology at Ludwig-Maximilians-Universitaet (LMU), have carried out a study to determine the degree to which people show concern for robots and behave towards them based on moral principles.According to Sari Nijssen, the study set out to answer the following question:" Under what circumstances would adults be willing to sacrifice robots to save human lives?" The participants were faced with a hypothetical (假设的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized (人性化的) to various degrees or a robot that was clearly recognizable as a machine.The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it. Situations that included vivid stories in which the robot was described as a merciful being or as a creature with its own understandings, experiences and thoughts, were more likely to stop the study participants from sacrificing it in the interests of anonymous (无名的) humans. "This result indicates that our study group attached a certain moral status to the robot," says Paulus. "One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could come into conflict with their intended function—to be of help to us."（1）What has become a concern about robots?A. How to humanize them.B. How to treat them in life.C. How to use them effectively.D. How to find more applications.（2）In the study the participants probably have to decide ________.A. when to sacrifice a robotB. where to experience risksC. which robot to work withD. what robots should be like（3）What can be inferred from Paulus' words?A. Humanized robots offer less help to people.B. Humanizing robots too much may be improper.C. Certain moral status should be attached to robots.D. Conflicts often happen between humans and robots.（4）Which of the following would be the best title for the text?A. Robots, A Must for FutureB. Humanized Robots, A New TrendC. Robot Saved, People Take the HitD. Humanized Robots, Replace Human【答案】（1）B（2）A（3）B（4）C【解析】【分析】本文是一篇说明文，随着越来越多的机器人具有人性化，它们承担越来越多样化的专业和日常任务，人们如何看待他们，如何对待他们的问题变的迫在眉睫。

Supercomputers which can analyse blood samples and predict which patients are likely to become seriously ill could save tens of thousands of lives a year, it was revealed last night, according to The Daily Express.The artificial intelligence (AI) system, developed at University College London and set to be piloted in NHS hospitals later this year, will screen "at risk" patients so doctors can take early action to prevent death or serious illness. Prof Young, a consultant surgeon at Southend University Hospital, said: "I am so excited about this form of technology." Instead of people getting sick or dying because they are not picked up in time, this will allow us to step in earlier which will save lives and an enormous amount of money. "I think the potential of AI in healthcare like this is as big as the Industrial Revolution was—and signals a completely new example in the way we manage healthcare."The technology is the brainchild of Dr Vishal Nangalia, a consultant at the Royal Free Hospital in London. He used AI to analyse a billion stored blood samples from 20 different UK hospital trusts dating back up to 12 years. Computers assess blood test results by picking up subtle changes in red and white blood cells, suggesting a patient is going downhill.He found the technique forecast outcomes of patients with kidney problems with up to 95 per cent accuracy. Traditional methods highlighting serious patient concerns picked up as few as 16 percent of patients who went on to die. "This gives us the opportunity not only to save lives but to prevent serious illness, making the health service not only safer but more efficient." Prof Young said, "Instead of waiting for people to get worse, we will be able to treat them earlier."（1）What does the underlined phrase "screen" in Paragraph2 mean?A. comfortB. treatC. spotD. nurse（2）How do supercomputers help save lives?A. By storing blood samples.B. By analyzing patients' cases.C. By observing changes in blood cells.D. By assisting doctors with their operations.（3）Why did Professor Young mention the Industrial Revolution?A. To show the influence of AI.B. To stress the importance of health care.C. To introduce the topic of supercomputers.D. To present the achievement he has accomplished.（4）What do we know about the new technology?A. It helps patients recover earlier.B. It has helped save thousands of lives.C. It will promote the health service greatly.D. It is intended for patients with kidney diseases.【答案】（1）C（2）C（3）A（4）C【解析】【分析】本文是一篇说明文，介绍超级计算机能够分析血样并预测哪些病人可能会患上重病，每年可以挽救数万人的生命。

When vultures feel threatened they vomit, and the smell of vomited-on dead bodies puts of most predators. Throwing up allows the vulture to fly away more quickly-and the vomit can hurt the aggressor's eyes and face.Opossum (负鼠)In some ways opossums have it easy. In order to become "dead", they don't have to fax anyone a death certificate. They just lie there with their tongues hanging out with the smell of dead flesh, sometimes for hours, effectively convincing potential predators they can find a much fresher meal elsewhere. Even if they keep getting attacked, they won't move any more than a human statue until the threat has passed.Hoatzin (磨雉)Hold your nose and meet the hoatzin, a bird of distinctions, not the least of which is that it smells like fresh cow shit. The animal mostly eats leaves and it's the only bird known to digest by fermentation, like a cow. This process is what causes its smell and has earned it the nickname the "stink birdMillipedes (千足虫)Millipedes are tricky. For starters they look wormy. Their name is deceptive, too: Their legs number about 750. Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.Sea Hare (海兔)The graceful sea hare is plain in taste in the first place, so it's not the most popular dish in the seafood chain. Nonetheless this type of sea creature has a pretty creative smell-related defense that is almost the opposite of its smelly companions on this list. The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.Researchers using lobsters (2-f) as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don't know how appealing it is.（1）The sea hare defends itself from predators by ________.A. becoming plain in taste at the discovery of a predatorB. giving out purple ink to make itself invisible to predatorsC. releasing substance to make predators unable to smell itD. giving off smelly gas to try to drive predators away（2）Which of the following statements is TRUE according to the passage?A. The vulture carries bacteria so that predators dare not get close to it.B. The opossum fakes its death to avoid being targeted by predators.C. The hoatzin eats cow shit so that it is nick-named as "stink bird".D. The gas released by millipede was basically harmless.（3）The species that enjoys more than one defense mechanism is ________.A. vultureB. opossumC. millipedeD. sea hare【答案】（1）C（2）B（3）C【解析】【分析】本文是一篇说明文，介绍了一些野生动物是如何进行自身防御的。

The US team say the results, published in Nature, are "striking" and should encourage research efforts.Tests in humans could begin in months. But even if these go well, a licensed vaccine for widespread use to protect those at most risk -such as pregnant women -would still be years away, experts advise. Zika has been spreading across Central and South America and, most recently, Africa. More than 60 countries and territories now have continuing transmission(传播) of the disease, which is carried by mosquitoes. The virus causes serious birth damages during pregnancy and has been declared a global public health emergency.Now, developing a vaccine for pregnant women to protect their unborn babies is an international research priority(优先事项). US scientists from the Walter Reed Army Institute of Research, the Beth Israel Deaconess Medical Center and Harvard Medical School tested two types of Zika vaccine in mice – one based on bits of genetic(基因的) code from the virus and another that is an inactive (and therefore harmless) copy of Zika. Both worked well, protecting every mouse that was immunised against the virus. In comparison, all of the mice not given the vaccine caught Zika after they were exposed to it.Researchers say they will push ahead with developing the needed virus vaccine. There are many existing vaccines for other disease that use this type of technology, while there are relatively few DNA-based vaccines. Of course, future tests will need to check the vaccine is safe and effective in humans, as well as how long the immunity might last.（1）If the tests in humans go smoothly, .A. a vaccine for use in the laboratory will be still be years away.B. pregnant women in Africa will be the first to benefit from the vaccine.C. a licensed vaccine will still not be accessible in a short term.D. The Zika virus will cause less serious birth defects during pregnancy in months.（2）Which of the following statements is NOT true?A. many countries are actively involved in the research of the Zika vaccine.B. US scientists have tested more than two types of Zika vaccine in mice.C. None of the mice given the vaccine caught Zika.D. It is still unknown whether the vaccine is safe and effective.（3）Which can be the best title for the passage?A. Zika vaccine 'works very well' in miceB. Zika vaccine still has a long way to goC. International researches into Zika have paid offD. More attention has been paid to Zika vaccine【答案】（1）C（2）B（3）A【解析】【分析】本文是一篇说明文，介绍了科学家发现一种实验性疫苗可以保护小鼠免受寨卡病毒侵袭。

My two- and four-year-old boys love to win, whether they're racing their bikes down the sidewalk or just finishing their snacks. It's true that those with high status, from world leaders and prize winners to athletes and movie stars, are people we like and respect. A recent study published in Nature Human Behaviour showed that we seem to have an innate (天生的) preference for high-ranking peoples—but only if those people aren't hurtful toward others.Researchers showed toddlers (aged 21 to 31 months) a scene where two puppets (木偶) approached one another from opposite sides of a stage and one bowed to let the other pass first. Asked which puppet they liked better, 18 of the 21 toddlers in the experiment reached for the puppet who had been allowed to pass. Because respect from others is a marker of status, this suggests that children have a preference for those with a higher status—even before age three. However, the results were quite different when two puppets approached one another and one used force to knock the other down before continuing to the other side. In this case, 18 of the 21 toddlers reached for the one who was knocked down. As the researchers concluded, "When approaching others, very young children care not only who wins, but also how." The previous experiment has shown that toddlers know about social status, but this experiment went one step further by proving they have an obvious preference for high status. Since the participants were so young, this might even be an innate human preference.In a word, this new research suggests that young children appreciate people who do well while at the same time doing good to others. So, when my four-year-old thinks that he has to get his shoes on first, I'll keep reminding him that helping his brother so they both finish faster is what winning is all about.（1）What do we tend to do according to the first paragraph?A.Seek challenges all the time.B.Admire high-ranking people.C.Take advantage of high status.D.Hurt others with offensive words.（2）Why did toddlers prefer the puppet allowed to pass?A.It looked adorable.B.It behaved smartly.C.It seemed polite.D.It was respected.（3）What can we infer from the latter study?A.Slower people are better loved by toddlers.B.People naturally dislike unkind behavior.C.Toddlers care little about high social status.D.Being helpful contributes to being supported.（4）What should we do when we encourage children to win?A.Instruct them to use proper and creative ways.B.Advise them to be as hardworking as possible.C.Remind them to be considerate to other people.D.Tell them to try to cooperate with someone else.【答案】（1）B（2）D（3）B（4）C【解析】【分析】本文是一篇说明文，介绍了人们更倾向于喜欢和尊敬地位高而又无害于他人的人，这似乎是一种天性，即使是蹒跚学步的孩子也是如此。
